In addition, there are provided skin cosmetics which do not cause stickiness after their use, are excellent in rough skin improving and preventing effects, wrinkle preventing and improving effects, dinginess improving effect and the like, and also have an effect in providing the skin with smoothness and liveliness. Also, in the case of skin cleansing compositions, they exert such effects that they can provide the skin with liveliness and moistness after washing and can effectively remove fishy and ammonia smells or the like filthy smell adhered to the hand, the skin and the like. A skin cosmetic characterized in that it contains (A) at least one substance selected from seed extracts and seed hull extracts of a plant belonging to the genus Carya of the family Juglandaceae in an amount of from 0.00005 to 2% by weight as solid matter, and (B) an additive agent.

FIELD OF THE INVENTION

[0001] This invention relates to lotion, emulsion, cream, pack, hairtonic, skin cleansing composition and the like cosmetics for skin use.

BACKGROUND OF THE INVENTION

[0002] In general, human cuticle surface (the skin) is covered withsebaceous membrane and transpiration of moisture is appropriatelyinhibited thereby, so that insufficient moisture in the skin is apt toentail rough skin and the like and cause wrinkles. Thus, it is veryimportant from the viewpoint of skin health to maintain skin moisturewithin a suitable range. However, since the sebaceous membrane isfrequently removed by the use of a skin cleansing composition at thetime of face washing or bathing, the skin moisture is apt to be removedtemporarily. Because of this, lotion, emulsion, cream, essence and thelike moisture keeping cosmetics are used after face washing or afterbathing for the purpose of supplying and maintaining moisture in theskin. In general, glycerol, 1,3-butylene glycol, sorbitol and the likepolyhydric alcohols, pyrrolidonecarboxylic acid salts and the like areblended as moisture keeping agents in moisture keeping cosmetics, butthough these agents are excellent in moisture retaining property underhigh humidity, their moisture retaining property under low humidity ispoor, their persistency of moisture keeping effect is not sufficientand, in some cases, they conversely accelerate rough skin by absorbingthe skin moisture.

[0003] Accordingly, studies have been carried out in recent years onvarious moisture keeping components. For example, studies have beenconducted on various substances, such as chitin, chitosan andderivatives thereof, protein hydrolysates, hyaluronic acid and the likeacidic mucopolysaccharides, plant extracts and the like, as moisturekeeping components having high water retaining ability under lowhumidity. However, when these moisture keeping components were blendedin cosmetics, it caused an disadvantage of conversely resulting inunpleasant stickiness due to their high moisture keeping ability. Inaddition, in order to make up for these disadvantages, an ester oil, ahydrocarbon oil and the like various oily components and oily componentscontaining unsaturated fatty acids and derivatives thereof have beenformulated in various cosmetics, but periodical stability of thecosmetics prepared by using these oily components was not sufficient dueto their periodical oxidation and deterioration. Accordingly, variousoil soluble antioxidants have been used in skin cosmetics with the aimof attaining stabilization of the products and prevention from theoxidation of sebum after their application, but their periodicalstability is not sufficient yet, and they do not have both of theeffects to prevent and improve rough skin.

[0004] On the other hand, for the purpose of reinforcing the effects toprevent and improve rough skin, attempts have been made to formulatevarious anti-inflammatory agents, such as glycyrrhizic acid salts,glycyrrhetinic acid derivatives, azulene derivatives and the like,together with these components and vitamins having high moisture keepingeffect (JP-A-6-32728, U.S. Pat. No. 5,686,086, U.S. Pat. No. 5,962,000).

[0005] However, it is the present situation that a skin cosmetic whichcan add sufficient moisture keeping effect and moisture to the skin andis also periodically stable while showing good used feeling cannot beobtained even by these methods. What is more, there are no reports on acosmetic which simultaneously has the effect to prevent and improvegeneration of wrinkles due to aging, ultraviolet rays and the like, bypreventing and improving rough skin, the effect to provide liveliness bysoftening the skin, the effect to improve dinginess of the skin, theeffect to prevent aging of the skin and the like.

[0006] Also, in the case of body shampoo, cleansing cream and the likeskin cleansing cosmetics which are used at the time of washing, thereare problems regarding loss of moisture from the skin caused by washingand their stimulation to the skin. Because of this, concern has beendirected toward the development of a skin cleansing composition whichcan add moistness and liveliness to the skin without losing excessmoisture therefrom and can wash and smooth out the skin without spoilingthe refreshed feeling.

[0007] In addition, it is important also as a function of the skincleansing composition to remove not only stains but also unpleasantsmells remained on hands, the skin and the like, such as ammonia andfishy smells, or the like filthy smells, but in reality, it is thepresent situation to rely on masking by perfume and the like because itis unable to remove these smells efficiently. Furthermore, it isnecessary to carry out excess washing for sufficiently removing stainsand smells, but it causes problems such as chapping of the skin, so thatit is the present situation that moistness and liveliness can hardly beretained on the skin after washing without using lotion, cream and thelike moisture keeping cosmetics.

SUMMARY OF THE INVENTION

[0008] Under such situations, the invention contemplates solving theaforementioned problems and thereby providing periodically stable skincosmetics which can add sufficient moisture keeping effect and moistnessto the skin and also have good used feeling. Also, regarding skincleansing compositions, it contemplates providing a skin cleansingcomposition which can effectively remove fishy and ammonia smells andthe like filthy smells adhered to hands, the skin and the like.

[0009] In addition, it contemplates providing a skin cosmetic whichshows light feeling during its use, does not cause stickiness after itsuse and is excellent in the rough skin-preventing and improving effects,the wrinkles-preventing and improving effects and the skindinginess-improving effect, simultaneously having the effect to keep theskin smooth and young thereby providing liveliness and the like.

[0010] As a result of intensive studies carried out with the aim ofsolving the aforementioned problems, the present inventors have noticedthat extracts of seeds and seed hulls of a plant belonging to the genusCarya of the family Juglandaceae can attain the aforementioned objects.

[0011] That is, it was found that the aforementioned objects of theinvention can be attained by skin cosmetics which contain theaforementioned extract and an anti-inflammatory agent or oil solubleantioxidant at a specified ratio.

[0012] In addition, taking note of the function of the aforementionedextracts to remove ammonia and fishy smells and the like filthy smellsand its effect to add liveliness and moistness to the skin afterwashing, it was found that the objects can be attained by a cleansingcomposition which contains a specified fatty acid soap at apredetermined ratio as the washing active ingredient and theaforementioned extract at a predetermined ratio, and also contains anamphoteric surface active agent and/or alkanolamide type nonionicsurface active agent as occasion demands. The invention has beenaccomplished based on such knowledge.

[0013] Accordingly, the invention provides,

DETAILED DESCRIPTION OF THE INVENTION

[0023] The skin cosmetics of the invention contain, as a component (A),at least one substance selected from seed extracts and seed hullextracts of a plant belonging to the genus Carya of the familyJuglandaceae. Production method of the extract is not particularlylimited, and the extract of interest can be obtained, for example, bysubjecting seeds and/or seed hulls of a plant belonging to the genusCarya of the family Juglandaceae, illustratively a hickory (C. tomentosa(Poi Nutt)), pecan (Carya illinoensis (Wang) K. Koch) or the like, assuch or after drying, to heating reflux together with one or two or moresolvents selected from hydrocarbon compounds, esters, ketones, ethers,halogenated hydrocarbon compounds, alcohols and water, or by soakingthem in such solvents. Preferred is an extract prepared by extractingseed hulls of pecan which belongs to the genus Carya of the familyJuglandaceae with water and/or one or two or more of lower alcohols, andmore preferred extract is their water extract.

[0024] The method shown below is an illustrative example of theextraction method (cf. JP-A-2000-72686).

[0025] Firstly, the seeds and/or seed hulls to be treated are pulverizedas such or after drying and then subjected to extraction treatment usingan extraction solvent in an amount of approximately from 5 to 100 timesof their weight. The extraction temperature is optionally selected inresponse to the kind of extraction solvent to be used. For example, whenthe extraction solvent is water, the extraction temperature is generallyfrom about 20 to about 120° C., preferably from about 90 to 110° C.Also, when the extraction solvent is a lower alcohol, it is generallyfrom about 20 to about 50° C., preferably room temperature. Also, theextraction time may be approximately from 5 to 60 minutes when theextraction solvent is water, but a period of approximately from 24 to 96hours is appropriate in the case of a lower alcohol.

[0026] After the extraction treatment, the extract is taken out bycarrying out solid-liquid separation by filtration or the like means,the extraction solvent is evaporated in accordance with a general methodand then a drying treatment is carried out as occasion demands, therebyobtaining the extract.

[0027] Amount of the aforementioned extract to be contained as thecomponent (A) of the invention is selected within the range of from0.00005 to 2% by weight, as solid matter based on the entire amount ofthe cosmetics. When this amount is less that 0.00005% by weight,persistency of the moisture keeping effect, rough skin-preventing andimproving effect, wrinkles-preventing and improving effect, and theeffect to make the skin smooth and thereby provide liveliness becomeweak. Also, when used in a skin cleansing composition, effective removalof ammonia and fishy smells and the like filthy smells cannot be made.When it exceeds 2% by weight on the other hand, not only the periodicalstability becomes poor but also it is disadvantageous from the viewpointof cost, and creaminess of foams becomes poor when used in a cleansingcomposition. From the above points of view, preferred amount of saidcomponent (A) to be contained is within the range of from 0.0001 to 1.5%by weight as solid matter, more preferably from 0.0005 to 1% by weightas solid matter.

[0028] In this connection, according to the invention, the extract ofcomponent (A) is formulated as the extract itself, or as itsconcentrated or dried preparation. Accordingly, when said extractcontains an extraction solvent, the solid content is obtained as acalculated value by determining amount of the solvent using a gaschromatography or high performance liquid chromatography.

[0029] An additive agent is added to the skin cosmetics of the inventionas the component (B).

[0030] Examples of the additive agent include an anti-inflammatoryagent, an oil soluble antioxidant, a fatty acid soap having from 8 to 20carbon atoms, an amphoteric surface active agent, an alkanolamidenonionic surface active agent and the like.

[0031] The anti-inflammatory agent is not particularly limited, and itsuseful examples include glycyrrhizic acid, glycyrrhetinic acid, azulene,allantoin, photosensitizer, ketoprofen, ibuprofen, camphor, thymol,piroxicam, salicylic acid, hydrocortisone, acetaminophen, aspirin,indometacin, bufexamac, saponin, oryzanol, ε-aminocaproic acid and saltsthereof, ester derivatives and the like. According to the invention,among these agents, glycyrrhizic acid or a derivative thereof,glycyrrhetinic acid or a derivative thereof, azulene or a derivativethereof, and allantoin or a derivative thereof are suitably used.

[0032] These anti-inflammatory agents can be obtained for example in thefollowing manner.

[0033] Glycyrrhizic acid can be obtained generally by treating anextract of licorice (Glycyrrhiza glabra) with a mineral acid or thelike, and its salt is obtained by neutralizing it with potassiumhydroxide, ammonia or the like alkali. Also, glycyrrhetinic acid isobtained when glycyrrhizic acid is decomposed using sulfuric acid or thelike, and a derivative thereof can be obtained by allowing it to reactwith stearyl bromide or the like.

[0034] Regarding azulene, corresponding compounds are obtained fromvarious essential oils; for example, guaiazulene is obtained fromessential oil of Guaiacum officinale L. or guaiol. In addition, it canalso be obtained by a synthesis method in which octalin is used as thestarting material and, via a diketone and an unsaturated ketone, finallysubjected to dehydrogenation (Plattner method), or in which pyrimidineis used as the starting material and converted into a glutaconaldehydederivative, and a condensation product of this with cyclopentadiene isheated (Ziegler process).

[0035] Allantoin is distributed in rootstocks of Symphytum officinaleL., leaves of Platanus orientalis L. and the like, and it can beobtained by extracting from them but can also be obtained by a synthesismethod in which bromine is allowed to act upon hydantoin and urea or itis condensed from two urea molecules and one glyoxylic acid moleculeunder compression and heating. In addition, its derivatives includeallantoin chlorohydroxyaluminum, allantoin dihydroxyaluminum and thelike.

[0036] As the anti-inflammatory agents, commercially available productsmay be used.

[0037] According to the invention, the aforementioned anti-inflammatoryagents may be used alone or as a combination of two or more. Also, thecontent is selected within the range of from 0.005 to 10% by weightbased on the total amount of the cosmetic composition. When this amountis less than 0.005% by weight, rough skin preventing and improvingeffects and wrinkle preventing effect become weak, and when it exceeds10% by weight on the other hand, not only it causes stickiness and aproblem regarding stability but also it is disadvantageous in terms ofcost. From such point of view, the amount of said anti-inflammatoryagent to be contained is preferably within the range of from 0.01 to 7%by weight, more preferably from 0.02 to 5% by weight.

[0038] According to the invention, it is desirable that blending weightratio (A/B) of the aforementioned component (A) and anti-inflammatoryagent (B) is within the range of preferably from {fraction (1/50)} to{fraction (10/1)}, particularly preferably from {fraction (1/30)} to{fraction (5/1)}, from the viewpoints of the persistency of moisturekeeping effect, rough skin preventing effect, wrinkles preventing andimproving effects, skin softening effect and the like.

[0039] Regarding the oil soluble antioxidant of the invention, there isno particular limitation, and its useful examples include α, β, γ orδ-tocopherol and the like vitamin E components, dl-α-tocopherol acetateand the like vitamin E derivatives, retinol, 3-dehydroretinol and thelike vitamin A components, retinol acetate, retinol palmitate, retinal,retinoic acid or a salt thereof, ethyl retinoate, butyl retinoate andthe like esters, retinyl phosphate or a salt thereof and the likevitamin A derivatives, liver oil extracted from fishes containing alarge amount of vitamin A, ascorbic acid palmitate and the like vitaminC derivatives, butyl hydroxy anise (BHA), dibutyl hydroxy toluene (BHT),eugenol, isoeugenol, propyl gallate and sorbic acid, as well as sesaminand sesame oil containing the same in a large amount, and flavonoids.Among them, vitamin E or a derivative thereof, vitamin A or a derivativethereof and a vitamin C derivative are preferably used.

[0040] According to the invention, the aforementioned oil solubleantioxidants may be used alone or as a combination of two or more. Also,the content is selected within the range of from 0.001 to 10% by weightbased on the total amount of the cosmetic composition. When this amountis less than 0.001% by weight, rough skin preventing effect, wrinklespreventing and improving effects and dinginess improving effect do notbecome sufficient, and when it exceeds 10% by weight on the other hand,the sense of touch at the time of use or after use, such as poorspreading or generation of stickiness or the like, is worsened, and itmay also cause a problem regarding periodical stability. The amount ofsaid oil soluble antioxidant to be contained is preferably within therange of from 0.005 to 8% by weight, more preferably from 0.01 to 5% byweight.

[0041] According to the invention, it is desirable that blending weightratio (A/B) of the aforementioned component (A) and oil solubleantioxidant (B) is within the range of preferably from {fraction (1/20)}to {fraction (5/1)}, particularly preferably from {fraction (1/10)} to{fraction (3/1)}, from the viewpoints of the rough skin preventingeffect, wrinkles improving effect, effect to provide moistness andliveliness to the skin, dinginess improving effect and the like.

[0042] In case that the cosmetics of the invention are skin cleansingcompositions, a fatty acid soap having from 8 to 20 carbon atoms isadded as the component (B). The fatty acid soap having from 8 to 20carbon atoms of the invention is an alkali salt of a fatty acid havingfrom 8 to 20 carbon atoms and is the active washing ingredient. Thefatty acid having from 8 to 20 carbon atoms is not particularly limitedand can be used by optionally selecting it from saturated or unsaturatedfatty acids having from 8 to 20 carbon atoms conventionally used as thematerial of fatty acid soaps. Its illustrative examples include caprylicacid, capric acid, lauric acid, myristic acid, palmitic acid, stearicacid, oleic acid, linoleic acid, coconut oil fatty acids, palm kerneloil fatty acids, sunflower oil fatty acids, hardened tallow fatty acidsand the like. In addition, examples of the ion pair forming alkaliinclude an alkali metal hydroxide, ammonia, an organic amine, a basicamino acid and the like, and their illustrative examples include lithiumhydroxide, sodium hydroxide, potassium hydroxide, triethanolamine,lysine, arginine and the like, of which sodium hydroxide and potassiumhydroxide are preferred.

[0043] According to the invention, the aforementioned fatty acid soapsmay be used alone or as a combination of two or more. Also, the contentis selected within the range of from 5 to 80% by weight based on thetotal amount of the cosmetic composition. When this amount is less than5% by weight, sufficient foaming ability cannot be obtained, and when itexceeds 80% by weight on the other hand, a strained feeling afterwashing becomes strong. When the foaming ability, strained feeling afterwashing and the like are taken into consideration, the content is withinthe range of preferably from 7 to 80% by weight, particularly preferablyfrom 10 to 80% by weight.

[0044] According to the cleansing composition of the invention, in orderto improve its foam quality, stability and the like, an amphotericsurface active agent and/or an alkanolamide nonionic surface activeagent can be contained as the component (B), as occasion demands, inaddition to the fatty acid soap having from 8 to 20 carbon atoms.

[0045] Examples of the amphoteric surface active agent include betainealkyldimethylaminoacetate, betaine amidopropyldimethylaminoacetate, analkylhydroxyethylmethyl sulfobetaine, an amidoamino acid salt, analkyliminodicarboxylic acid salt, an alkyliminodiacetic acid salt, analkylaminoethylglycine salt and the like, of which betainealkyldimethylaminoacetate, betaine amidopropyldimethylaminoacetate, anamidoamino acid salt and an alkyliminodicarboxylic acid salt arepreferred, and betaine amidopropyldimethylaminoacetate, an amidoaminoacid salt and an alkyliminodicarboxylic acid salt are more preferred.

[0046] On the other hand, the alkanolamide nonionic surface active agentis prepared by the condensation reaction of a fatty acid with analkanolamine or the aminolysis reaction of oil and fat with analkanolamine. Examples of the fatty acid which forms said compoundinclude caprylic acid, capric acid, lauric acid, myristic acid, palmiticacid, stearic acid, oleic acid, linoleic acid, coconut oil fatty acids,palm kernel oil fatty acids, sunflower oil fatty acids, hardened tallowfatty acids and the like, and examples of the alkanolamine includemonoethanolamine, diethanolamine, monoisopropanolamine and the like.Examples of the oil and fat which form said compound include coconutoil, palm kernel oil, sunflower oil, hardened beef tallow and the like.In addition, a 1:1 type or 1:2 type is prepared depending on thereaction condition, but preferred is a 1:1 type.

[0047] According to the invention, the aforementioned amphoteric surfaceactive agents may be used alone or as a combination of two or more, andthe aforementioned alkanolamide nonionic surface active agents may beused alone or as a combination of two or more. Also, one or moreamphoteric surface active agents and one or more alkanolamide nonionicsurface active agents may be used in combination. In addition, it isdesirable that the total content of the amphoteric surface active agentsand/or alkanolamide nonionic surface active agents is within the rangeof from 0.1 to 10% by weight, based on the total amount of the cosmeticcomposition. The amount within the above range is desirable, becauseeffect of the surface active agent is sufficiently exerted and the senseof touch after completion of washing becomes good without sliminess.More preferred amount of said component is within the range of from 0.5to 8% by weight.
